# Post the report to Slack

Some people live in Slack, not email. A Slack destination uploads the file to a channel as one post, with a message you template, and Slack previews the workbook in the thread. A channel is given by name or ID; a person by user ID, for a DM.

Recorded from a real run: the command, then the post in Slack.

  format: xlsx
  columns:
    net: {format: "#,##0.00"}
  destination:

```

```yaml
destinations:
  slack:
    target: dev

      dev: {type: slack, token: "{{ env_var('DRE_SECRET_SLACK_BOT_TOKEN') }}"}
```

terminal

```bash
dre run slack_post
```

### What to notice

-   The bot token stays in an environment variable and is never logged.
-   Scopes the Slack app needs: files:write always, plus channels:read and groups:read to post to a #name (or give the channel ID instead). A DM also needs im:write and chat:write.
-   The bot has to be in the channel: /invite it first. A private channel needs the invite too.
-   A missing scope or channel is reported with what to fix, and the output stays in target/.
